Ing.(grad.) Kurt Gerhard from Fernwald founds STAKU Stahl- und Kunststofftechnik GmbH with head offices in Giessen.


The company moves to its own offices and production facilities on an area of approx. 3,000 m² in the Bahnhofstraße 33 – 35, Lich. Operations focus on the development and production of equipment and plants for chemical surface treatment. Complete pickling lines for wire, strip and pipes are exported worldwide, from Argentina to Saudi Arabia.

These also include exhaust air and waste water treatment facilities for environmental protection.


Thanks to qualified personnel and external monitoring by TÜV Hesse, the company is approved as a specialist company in accordance with the German Water Resources Act (WHG) § 19, necessary for the construction and erection of HBV installations and the handling of water-hazardous substances.


STAKU shifts the company focus from chemicals to the electrolytic process technology sector for the pretreatment and finishing of metals and non-ferrous metals.


After completing his studies of processing engineering at the RWTH Aachen, Dipl.-Ing. Jörg Gerhard joins the family-owned company. In the modern laboratory, correspondingly qualified personnel now conduct research into new pretreatment and coating methods for continuous electrolysis processes.


ThyssenKrupp Stahl AG orders an electrolytic surface treatment line for car body panels. The strips have a width of 1,600 mm and are prepared electrolytically for the downline Galfan galvanising process. The treatment system is later marketed under the name e-clean within the e-systems product family.


Based on the e-clean technology, a complete strip tinning line for non-ferrous metal strips is built for the NA Group in Hamburg. With this combined plant, STAKU gains a reputation for itself as a leading company in the strip plant technology sector.


Jörg Gerhard, son of the founder, takes over STAKU- Stahl und Kunststofftechnik GmbH and founds a further company with the name STAKU-Anlagenbau GmbH, also with head offices in the Bahnhofstraße in Lich. This company is responsible for the development and worldwide sales of the galvanising lines. In the following years, strong sales contacts are made around the world.


After a long period of development, the first two electrolytic continuous-pass phosphating lines for the production of cold heading wire for screws, spark plugs, etc. are successfully commissioned by STAKU. With this new technology, the treatment times are reduced from previously 20 minutes to 6 seconds. In the following years, the phosphating process originally used is constantly further developed and improved.


To celebrate the company's 30th anniversary the e-phos process, a new zinc-calcium phosphate coating for the wire and strip industry with significant economic and ecological benefits, is registered for patent.


STAKU develops the new e-copp process, a electrolytic system for continuous copper plating of steel surfaces without additional pretreatment. Within a very short time, the new coating method is adopted by all the leading manufacturers from the welding wire industry and employed worldwide.


In March STAKU is granted the patent for the e-phos process under the number EP 1 574 601. The company's product range is presented for the first time under the name e-systems at the international Wire & Tube fair in Düsseldorf.


Inauguration of the completely new designed assembly shop with a space of 700 m2 and a hight of 7,5 meters. At the same time arised in the same building at the upper floor a new open-plan office with the space of 430 m2 and 15 work stations ergonomically designed according to the latest standard of knowledge. With this expansion STAKU is now able to assemble and wire and strip treatment lines up to 30 meters length for preacceptance.


Our new process e-molyphos resulted from the further development of our patented e-phos process: Electrolytic phosphating with simultaneous deposition of a lubricant - that means the metal surface receives a self-lubricating phosphate layer by deposition of a lubricant carrier and a lubricant in one step. This process is especially suitable at warm and cold forming of stainless steel and titanium.

The perfect surface for Strip, Wire & Profiles/Tube.
